Improvement in boring wells

IMPROVEMENT IN BORING WELLS.

Specification forming part of Letters Patent No. 47,729, dated-May 1G,1865.

To all whom it may concern:

Be it known that I, WALTER HYDE, of the city, county, and State of NewYork, have made new and useful Improvements in Well- Boring Machines 5and I do hereby declare the following to be a clear and exactdescription of the same, reference being had to the annexed drawings,making part of this specification, in which- 'Figure 1 is a sideelevation ofthe machine. Fig. 2 is a section on the line zum, Fig. 3.Fig. 3 is a plan or top view.

Similar letters refer to like parts in thedifferent gures.

The objects of 'this improvement are, rst, to operate the drill throughthe medium of a single continuous rope; second, to provide facilitiesfor arresting the motion of the drill without stopping the machinery;third, to provide facilities for changing the action of the motor Vfromthat of operating the drill to that of withdrawing it. l

On a sill', A, is erected a vertical frame or shears, B, near thesummit-of which is a pulley, C, over which the rope D passes. This isconnected at its upper end, E, with the stock of the drill-shaft,and onthe other side of the shears or derrick, passing downwardly, runs upon asheave, F, which is pivoted in a lever, Gr, which vibrates vertically,its downward motion being caused bythe cams H on the shaft P, and thereturn motion being given to the weightof the drill-stock as it makesits eiiective stroke. The rope D, on leaving the sheave in the lever,ascends and passes over sheave J, which rotates upon an axis, K, whichis bracketed to the shears, and from the sheave J descending it is woundupon the drum L, which holds all the reserve of rope beyond what isnecessary to reach from the drum to the head of the drill-stock.

A winch, M, isiitted upon the shaft of the drum L for winding up therope by hand, and a pawl, N, retains the drum in position with therequired tautness upon the rope D.

O is the iiy-wheel, upon Whose shaft P the cams H are placed, and Q is aspur-wheel,

which communicates by gearing 1t S T with the shaft of the rope-drum Lsoas to wind up the rope by motion applied to the shaft P.

When it is desired to stop the motion of the drill, it is done by meansof a lever, U, which operates a detent, V, which latter is thrown abovethe lever G, so as to hold it at the downward point of its stroke out ofthe effective range of the cams H. y

W is a lever operating a clutch, X, on the shaft P, so as to throw theWinding-up gear `Q R S T into action to draw the rope D and `withdrawthe drill or sand-bucket from the well or shaft.

Y are stays to sustain the shears or derrick B in a vertical positionaThe operation of the machine is as follows: The drill-stock with drillattached being suspended from the end of the rope, the shaft P isrotated, which brings the cams H in contact with the lever, which,drawing upon the rope,

elevates the drill and again releases it, so as` to cause the requiredlite intermittent motion.

As the drill works its way down, a portion of rope is let off from thedrum L by raising the paWl and allowing the drum to rotate a notch ortwo of the ratchet-wheel on its end. The requisite distance having beendrilled, the tool is withdrawn for the operation of removing thedetritus by the sand-pump, and this withdrawal is performed by movingthe lever U, which throws the detent V above the lever and holds thedrill suspended and at rest. The lever W then throws the clutch X ingear,

and rotates the drum L through the interposition of the gearing Q R ST,and the rope and drill are withdrawn from the Well.

The means of Aoperating the machine for lowering the sand pump or thedrill to its working depth are the winchM, the pawl being thrown out ofgear.

The windlass-drum on the side of the inachine is capa-ble of containinga thousand feet of rope, and is continuous, being always: in placewithout making connections of separate lengths.

The motor is run continuously, and the winding or drilling mechanism isapplied at pleasure or both thrown out of gear. y

It is sometimes necessary, on account of fissures in the rock or theaccumulation of debris, to withdraw the drill instantaneously,

and this is done by moving the hand-lever W,

which throws the winding-up gear into instant action. a

The prime motor which revolves the shaft P it is not necessary todescribe. It may be steam engine or other power.

The arrangement for driving pipe is fixed to the main post, and works insubstantially the same manner as those in ordinary use, except that thedevice which grasps the weight is secured to the rope by a screw in thesaine manner that the drill-rods are secured to the same.

The length of the stroke ofthe drill is regulated by the tension of thecord, and all the motions are effected without handling the rope, whichis often cold and nasty.

The drill-stock is suspended, and when the n drill comes to a crevice,perhaps oblique to its course, it has a natural tendency to follow it.The drill is then worked gently, so as at its lowest point merely totouch the rock, until. it has established a footing.

Having thus described my invention, what I claim therein as new, anddesire to secure by Letters Patent, is-

1. The combina-tion ofthe reserve rope-drum L, the sheave J thevibrating lever Gr and its pulley F, the upper pulley, C, the rope D,drillstock, and tripl'iing-cams, so that all the mo- Vby which thedrill-stock is withdrawn without detacliin g the rope or stopping themotion of thepriine motor.

3. The lever U, in combination with the plate V or other detent forarresting the motion ot the vibrating lever. Y

4 In connection with the subject-matter of the second claim, the leverW, as a means of changing the action of the motor-frame, a.vdrill-operating mechanism to a drill with drawing mechanism.

The above specification of my improved well-borin g apparatus signedthis 24th day of February, 1865.
